– Select Fixed exposure to set a fixed shutter speed.
Select the shutter speed for fixed exposure. (The values available depend on the value set
for the ALC mode.)
Maximum shutter [s]
Select a value in this field as the maximum speed of the shutter when the camera is in
Automatic exposure mode. The limit on the shutter speeds improves the motion performance.
A lower value increases sensitivity at the expense of increased motion blur.
This option is only available when
Automatic exposure is selected.
Default shutter [s]
Select a default shutter speed. The default shutter improves the motion performance in auto
exposure mode.
The camera maintains the selected default shutter speed as long as the light level of the scene
allows it.
This option is only available when
Automatic exposure is selected.
Select the Fixed shutter [s] for fixed exposure. (The values available depend on the value set
for the ALC mode).
Day/night
Select the appropriate mode from the drop-down list.
Auto - the camera switches the IR cut-off filter on and off depending on the scene illumination
level.
Monochrome - the IR cut-off filter is removed, giving full IR sensitivity.
Color - the camera always produces a color signal regardless of light levels.
Night-to-day switchover
Adjust the slider to set the video level at which the camera in Auto mode switches from
monochrome to color operation (-15 to +15).
A low (negative) value means that the camera switches to color at a lower light level. A high
(positive) value means that the camera switches to color at a higher light level.
(The actual switch-over point might change automatically to avoid instable switching.)
Iris priority - open vs. closed
Use the slider to adjust the iris opening to the specific requirements of the scene.
–
Iris open increases local sharpness and/or increases sensitivity.
– Iris close increases depth of field, which allows you to keep objects of interest in focus.
In scenes where a change of the iris opening affects the gain, closing the iris causes more
video noise and increases bandwidth. Increased motion blur may also occur when the iris
is more closed.
7.2.3 Enhance
All settings on this page except for Intelligent Noise Reduction are scene-mode specific. This
means that sharpness/noise suppression/HDR can be adjusted on each scene mode.
High dynamic range
The High dynamic range mode uses an electronic shutter to capture multiple images with
different exposure times and to reproduce a high-contrast frame. The output frame combines
the bright area captured by the high-speed shutter image and the dark area captured by the
low-speed shutter image. The result is that you can view details in both the bright areas
(highlights) and the dark areas (shadows) of a scene at the same time.
